U.S. stock markets open multiple times each week, and knowing the exact hours helps investors plan around news, earnings, and personal schedules. Regular trading sessions run on a predictable weekday calendar, while early closes and holiday shutdowns create occasional variations.
Below is a quick reference that captures the standard open and close times, key early close dates, and market holidays that affect when trading begins and ends.

Understanding Standard U.S. Market Hours
The primary U.S. equity exchanges operate on a consistent schedule during normal weeks. Both the NYSE and NASDAQ open at 9:30 AM ET and close at 4:00 PM ET, providing a six and a half hour window for price discovery and execution.
Pre-market trading begins as early as 4:00 AM ET, allowing institutional participants to react to news before the official open. After-hours sessions extend trading until 8:00 PM ET, offering flexibility for investors who cannot participate during the core session.
Together, these windows create a layered timeline where liquidity and volume shift throughout the day, influencing how orders are filled and priced during different periods of activity.
Early Market Closes To Watch
Certain days of the year feature early market closes at 1:00 PM ET, and these abbreviated sessions are typically scheduled around holidays or major events that fall on weekdays.
Common Early Close Dates
The dates can shift slightly year to year, but the pattern usually includes the day before Independence Day, the day after Thanksgiving, and the day before Christmas when those events land on a weekday.
How U.S. Holidays Affect Market Openings
U.S. markets are closed on New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Good Friday, Memorial Day, Juneteeth, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.
When a holiday falls on a Saturday, markets close early on the preceding Friday. When a holiday falls on a Sunday, markets are closed on the following Monday, creating a clear calendar of non-trading days that investors can plan around.
Global Interaction And Market Timing
Because digital communication links traders worldwide, U.S. market open becomes a focal point for global activity as Asian and European sessions overlap in the morning and afternoon hours.
These overlaps often coincide with higher volume and tighter spreads, while the period just before the U.S. open can see moves influenced by economic data and corporate announcements from other regions.
